Well said, DRR! I visit blogs that are specific to certain types of photography and hear so much animus and ignorance out there. Crop is all you need, primes rule, natural light is for idiots, L lenses are overpriced, only shoot with L lenses, etc., etc.
Each genre of photography has its own requirements and while any gear can be used, some gear works better than others. For example, shooting sports with a 3fps camera with limited AF is very difficult, but the same camera can produce amazing portraits. Large aperture lenses are wasted on landscape photographers, but necessary for sports & wildlife. A 85L is a horrible choice for most shots other than portraits, but can be used for other things. The list goes on and on and on....
To argue that any one technology, system, lens, or anything else is perfect (or pointless) is pure ignorance (or blatant commercialism supporting a sponsor).
Now that's well said. Thank you! More people need to think like this, because cameras are tools and many people can use them in many different ways. Some tools are better than others but in the right hands basic tools can accomplish amazing things.
